Stop promising delivery dates. Start forecasting them.
PtahCast runs Monte Carlo simulations against your team's real cycle time and throughput, so every date you give a client is a probability you can defend — not a guess you're hoping holds.
A real board, mid-project
This is an actual PtahCast board mid-sprint — priorities, epics, assignees, and per-column WIP limits. No mockup, no filler data.
"We stopped promising delivery dates and started forecasting them. Clients trust a range with a probability attached a lot more than they trust a confident guess — especially once they see we're usually right."
— CEO - StratumCodeThe old way breaks the moment reality doesn't cooperate
A single confident date is really just a guess wearing a suit. PtahCast replaces it with a distribution built from how your team actually works.
Old way
One date, no margin for error
A PM eyeballs the backlog and picks a date that sounds reasonable, and it goes straight into the SOW. There's no accounting for scope creep, sick days, or how much slower "In Review" actually runs than planned. When it slips, it's a surprise — to the client, and often to you too.
With PtahCast
A range, weighted by evidence
PtahCast runs thousands of simulated futures against your board's actual cycle times and throughput. You get an Aggressive (P50), Commercial (P85), and Safe (P95) date — plus an accountability log that tracks, honestly, whether you hit them.
Why Monte Carlo, and not just a bar chart
Gantt charts assume every task takes exactly as long as planned. Real work doesn't. Monte Carlo simulation accounts for that variance instead of pretending it away.
Every simulated trial is one possible future, built by resampling how fast this team has actually completed similar work before. The P50 line is what happens in half of those simulated futures — the outcome you'd bet on. P85 is the date you can put in front of a client and be right most of the time. P95 is the worst case you're prepared to defend if someone asks "what if everything goes wrong?" A bar chart can't tell you any of that. A distribution can.
What it does
One system, from the board your team works on to the report your client reads.
Board
A kanban board built for client work
Priorities, epics, assignees, and WIP limits per column — organized the way delivery teams actually triage work, not a generic to-do list.
Metrics
Flow metrics that explain the forecast
Cumulative flow, cycle time scatter, throughput run charts, and WIP over time — the same data your Monte Carlo forecast is built from, laid out so you can see why a forecast moved.
Forecasting
Monte Carlo delivery forecasts
10,000 simulated trials per run, weighted against your board's real throughput. Get an Aggressive (P50), Commercial (P85), and Safe (P95) date — and re-run it any time the backlog changes.
Accountability
A log of whether you were right
Every forecast you've ever run is saved, alongside the commitment date you gave the client. The accountability log shows, in plain sight, whether you delivered what you promised.
The engine underneath: every forecast PtahCast produces comes from a Monte Carlo simulation seeded with your board's own completed-ticket history — not an industry benchmark, not a formula someone typed into a spreadsheet once. Change your team or your backlog, and the next forecast changes with it.

Your agency's name on every forecast — not ours
On the Agency and Scale plans, client portals carry your logo and your color, not PtahCast's, on your own custom domain. Clients get a report; they never need to know what's running underneath it.
Why "Ptah"?
Ptah was the ancient Egyptian god of craftsmen, architects, and builders — patron of the people who turned plans into finished, standing things. Not the god of ideas. The god of the people who actually built them, on schedule, with their own hands.
That's the job PtahCast is built for. Your agency is a builder too — of software, of campaigns, of client trust. PtahCast doesn't do the building for you. It just tells you, honestly and with real numbers behind it, when the thing you're building will be done.
FAQ
What is Monte Carlo forecasting, exactly?
It's a simulation technique that runs a scenario — in this case, "finish the remaining backlog" — thousands of times, each time resampling from your team's actual historical cycle times and throughput. Instead of one predicted date, you get a full distribution of possible completion dates and how likely each one is.
Do I need a lot of historical data before PtahCast is useful?
No — it works from your first completed tickets. Forecasts get tighter and more confident as your board accumulates history, but you'll get a usable range from day one.
Can my clients see PtahCast branding?
On Starter and Growth, client portals are PtahCast-branded. On Agency and Scale, portals are fully white-labeled with your logo, your color, and your own custom domain.
How is this different from a Gantt chart or a single due date?
A Gantt chart bakes in one assumption per task and hides the uncertainty. Monte Carlo forecasting keeps the uncertainty visible — you see the full range of outcomes and how likely each one is, instead of a single date with no sense of how solid it is.
What happens if I miss a forecasted date?
It shows up in your accountability log. That's the point — PtahCast is built to keep a running, honest record of your forecasts versus what actually happened, not to hide the misses.
Can I re-run a forecast?
Yes, any time your backlog or team changes. A new simulation takes seconds and updates your Aggressive, Commercial, and Safe dates immediately.
